00:00:00.487 --> 00:00:03.937
Which of these makes an inference in statistics?
00:00:04.257 --> 00:00:07.727
Is it (A) computing a statistic from the sample?
00:00:08.257 --> 00:00:12.877
(B) Generating a random sample from a given population.
00:00:13.607 --> 00:00:19.127
(C) Applying conclusions drawn from a sample of a whole population.
00:00:19.717 --> 00:00:26.537
Or (D) working out the percentage of the population that exhibits a certain characteristic.
00:00:27.527 --> 00:00:35.147
Statistical inference is the process of using data analysis to deduce properties of a population.
00:00:36.337 --> 00:00:42.687
This means that we’re looking to make conclusions from a sample that could apply to the whole population.
00:00:43.607 --> 00:00:46.497
The correct answer is therefore option (C).
00:00:46.807 --> 00:00:52.467
An inference applies conclusions drawn from a sample of a whole population.
